Parity Broken Chiral Spin Dynamics in Ba${}_3$NbFe${}_3$Si${}_2$O${}_{14}$

Mickael Loire, Virginie Simonet, Sylvain Petit +9

The spin wave excitations emerging from the chiral helically modulated 120${}^{\circ }$ magnetic order in a langasite Ba${}_3$NbFe${}_3$Si${}_2$O${}_{14}$ enantiopure crystal were investigate…
